Apparently, if you hold the iPhone 4 by the antenna band, you'll lose your bars, your reception, and maybe even your call. As this video making the rounds showcases, holding the handset with your fingers pressed upon the antenna throws off your cell reception and effectively reduces your bars all the way down, in some cases, to zero.

Of course, it isn't yet clear if the real issue relates to an inaccurate showing of bars or a significant problem with the actual antenna. But as thousands unbox their iPhone 4s and activate the long awaited updated smartphone, you may want to give your device the finger so to speak and play the home game version of this video demonstration.

But as Paul noted earlier in his piece "iPhone 4 Screen Defects Reported," in every new product, manufacturing defects are almost inevitable. So as scattered but undocumented complaints similarly surface, there's a good chance we'll know in the coming hours and days if this example is an isolated incident (and let's hope that it is)... or if this is the first real bug and potential nightmare for the 4th generation iPhone and its customers.
